1 summary KS3 Science MyWorks Guide Chemistry KS3 Science: Chemistry Mini zes: 40 Super zes: 5 Extension zes: 4 Skills zes: 6 TOTAL 54 What are MyWorks zes? MyWorks zes are short individual learning tasks that can be set as homework or as a lesson task. There are four different types of in KS3 Science. Mini zes Mini zes are short, versatile zes suitable for most abilities. Each is worth 25 marks and takes around 10 minutes to complete. They cover small, bite-sized topics equivalent to around one lesson s work, and contain recap pages to remind students of the key points if they are struggling. Each matches a small section from one of the KS3 Science presentations, but can also be used independently of other products. Super zes Super zes are longer tests ideal for revision or assessment at the end of a larger unit of work. They are worth 50 marks and do not contain recap pages. Extension zes Extension zes are designed to stretch more able students. They either extend a previously covered topic by asking more difficult questions, or cover a new, but related topic. Questions are often more contextualised and require a greater degree of precision in finding the correct answer. The zes are out of 25 marks and include recap pages to explain where students may have gone wrong. Skills zes Skills zes are designed to cover important elements of the How Science Works requirements at KS3. The zes focus on three key areas: practical skills, data analysis and discoveries and society. Topics covered include planning and carrying out a fair, accurate and reliable experiment, representing results, drawing conclusions and the impact of science on society. The zes are out of 30 marks and contain recap pages to reinforce understanding. October /9
